FAQ
Hello,

I'm new on Redis, I started working two month ago on a small project and
like any project now is a big project than we expected.

The project run on a small server with 1.7 GB of RAM on amazon, and today
we found the unicorn instances down, because Redis grew and took all memory.

Maybe is normal and we will need add more memory, I don't know.

Could be posible optimize the server ?

Below the redis db info
